Lauren did say that the morning Peyton brought the fish into school, she felt like something was up. “Every morning, she feeds Mermaid. When I went over to where she was, she said, ‘No mommy, stay away, don’t come over here!’ Clearly, that was suspicious. I did notice that she spilled the fish food on the floor, so I just told her it was OK and that I would clean up the fish food. It never crossed my mind that she would put Mermaid in a sippy cup.”
